Added one for me in San Diego.

Hey Harman023, you're in the middle of the St Johns River!

you don't have to add your address, and it won't zoom all the way down, but you can get real close. Once you're close enough, click on the drop button that says add marker. A target will appear for your cursor, when you're close enough click on it. Then name the location with your screen name.
